High Efficiency Motors and Variable speed drive a powerful combination for carbon footprint and costs reduction

Reducing global power consumption is a major theme in responding to global warming. Climate conferences, soaring oil prices, energy taxation – the incentives for saving energy are more present than ever. Motors represents nearly 50% of the world electrical consumption. This article contains a review on new technologies toward electrical motors. Alternative Current (AC) and (DC) Direct Current are studied. Variable speed drive technology contributes greatly to motor efficiency. Therefore, it is included in this research. Maintenance and policy are also studied due to their significant impact.Energy savings can be up to 50% (all benefits combined).
